Your auditory perception is tested during an audiometry exam. The loudness (intensity) and tone (speed of sound wave vibrations) of a sound vary. Sound waves cause the inner ear's nerves to fire, which results in hearing. The sound then makes its way to the brain via nerve connections. Via the middle ear canal, eardrum, and middle ear bones, sound waves can enter the inner ear (air conduction). They can also travel through the bone conduction that occurs behind and around the ear. Simple tests that can be performed in the office might be used by your healthcare provider to assess your hearing. These could involve answering a series of questions and hearing sounds such as tuning forks, whispered voices, or tones from an ear examination scope. The type of hearing loss can be ascertained with the aid of a specialist tuning fork test. To assess hearing using air conduction, a tuning fork is tapped and held in the air on each side of the head. To evaluate bone conduction, it is tapped and pressed up against the mastoid bone, which is located behind each ear.
